Dell XPS first boot shut down
XPS 15 9560
been having this problem for a while and have seen multiple users post the same issue with no solutions. I have a XPS 9560 32gb ram, 4k touch screen that I rarely used (although it's 5 years old). Around summer of 2020 the battery just buggered and would not charge/turn on. I replaced the battery with a new one and all was fine. Fast forward a few months and the laptop would ALWAYS force shutdown on first boot on battery. Sometimes after 20 seconds, sometimes after 1 min, just straight up cut power, even when battery is full. I would then not be able to turn it on no matter what unless I plug in the adapter cord, after which I have to cycle through a few startup and force shut downs before it is able to properly turn on. Once it's on, then I am able to unplug the power and run it as normal, charges fine, great battery life, etc.
I've tried everything from reinstall windows, to upgrade/downgrade drivers, to drain onboard battery, to upgrade bios. Still the same everytime. It is for sure not thermals.
Anyone else have this and managed to get it solved? As it's still a very good and fast laptop, only annoyance is this first boot shutdown. THnx
